Abstract
We set out to design and synthesize bipodal ligands with the phenyl group as the spacer and varied the substitution on the spacer between ortho (L1), meta (L2), and para (L3). The respective ligands and complexes containing either p-cymene (PL1-PL3) or benzene (BL1-BL3) as the arene unit were synthesized and characterized successfully. The influence of the ligands due to substitution change on their coordination behavior was quite minimal; however, the differences were seen in the anticancer activity of the complexes. DFT studies revealed the structural variations between the three different substitutions, which was further confirmed by single-crystal X-ray diffraction studies. The anticancer activity of the complexes could be correlated with their rate of hydrolysis and their lipophilicity index as determined by UV-visible spectroscopy. The cell death mechanism of the active complexes was deduced to be apoptotic via staining assays, flow cytometry, and Western blot analysis.

Abstract
BACKGROUND Podophyllotoxin is a natural lignan which possesses anticancer and antiviral activities. Etoposide and teniposide are semisynthetic glycoside derivatives of podophyllotoxin and are increasingly used in cancer medicine. OBJECTIVE The present work was aimed to design and synthesize a series of 2, 4, 5-trideoxyhexopyranosides derivatives of 4'-demethylepipodophyllotoxin as novel anticancer agents. METHODS A divergent de novo synthesis of 2, 4, 5-trideoxyhexopyranosides derivatives of 4'-demethylepipodophyllotoxin has been established via palladium-catalyzed glycosylation. The abilities of synthesized glycosides to inhibit the growth of A549, HepG2, SH-SY5Y, KB/VCR and HeLa cancer cells were investigated by MTT assay. Flow cytometric analysis of cell cycle with propidium iodide DNA staining was employed to observe the effect of compound 5b on cancer cell cycle. RESULTS Twelve D and L monosaccharides derivatives 5a-5l have been efficiently synthesized in three steps from various pyranone building blocks employing de novo glycosylation strategy. D-monosaccharide 5b showed highest cytotoxicity on five cancer cell lines with the IC50 values from 0.9 to 6.7 mM. It caused HepG2 cycle arrest at G2/M phase in a concentration-dependent manner. CONCLUSION The present work leads to the development of novel 2, 4, 5-trideoxyhexopyranosides derivatives of 4'- demethylepipodophyllotoxin. The biological results suggested that the replacement of the glucosyl moiety of etoposide with 2, 4, 5-trideoxyhexopyranosyl is favorable to their cytotoxicity. D-monosaccharide 5b caused HepG2 cycle arrest at G2/M phase in a concentration-dependent manner.

Abstract
Podophyllotoxins and epipodophyllotoxins, possess excellent activity against both drug-sensitive and drug-resistant even multidrug-resistant cancer cells via inhibition of tubulin polymerization. Several podophyllotoxin/epipodophyllotoxin derivatives such as etoposide and teniposide have already been applied for cancer therapy, revealing their potential as putative anticancer drugs. Hybridization of podophyllotoxin/epipodophyllotoxin moiety with other anticancer pharmacophores is a promising strategy to develop novel drug candidates so as to overcome drug resistance and improve the specificity, and numerous of podophyllotoxin/epipodophyllotoxin hybrids exhibit excellent in vitro antiproliferative and in vivo anticancer potency. This review emphasizes the recent development of podophyllotoxin/epipodophyllotoxin hybrids with potential application for cancer therapy covering articles published between 2010 and 2020. The mechanisms of action, the critical aspects of design as well as structure-activity relationships were also summarized.

Abstract
Novel thiourea (5a, 5b) and thiazolidinone derivatives (6a, 6b) were synthesized by hybridizing molecules starting from the compound 6-(4-phenylpiperazin-1-yl)pyridin-3-amine (4) which is known to show anticancer activity. The synthesis of the leading compound was carried out by using 1-(5-nitropyridin-2-yl)-4-phenylpiperazine (3) which was obtained by a novel method of the reaction of 2-chloro-5-nitropyridine (1) and N-phenylpiperazine (2). The structures of the compounds were confirmed using FTIR, 1 H NMR, 13 C NMR, HRMS spectroscopic methods and elemental analysis. The organic molecules were tested for their anticancer activities against prostate cancer (PC) cell lines: DU 145, PC-3 and LNCaP. As the compound 5a exerted the highest cytotoxic activity, IC50 concentrations of compound 5a were further investigated in terms of morphology, colony-forming ability, RNA expression, fragmented DNA and cell cycle distributions of PC cell lines. Overall data revealed that compound 5a treatment induces apoptosis and DNA fragmentation in PC cell lines and inhibits cell cycle progression resulting in the accumulation of cells in either the G1 or the S phases.

Abstract
Podophyllotoxin and its related aryltetralin cyclolignans belong to a family of important products that exhibit various biological properties (e.g., cytotoxic, insecticidal, antifungal, antiviral, anti-inflammatory, neurotoxic, immunosuppressive, antirheumatic, antioxidative, antispasmogenic, and hypolipidemic activities). This Review provides a survey of podophyllotoxin and its analogues isolated from plants. In particular, recent developments in the elegant total chemical synthesis, structural modifications, biosynthesis, and biotransformation of podophyllotoxin and its analogues are summarized. Moreover, a deoxypodophyllotoxin-based chemosensor for selective detection of mercury ion is described. In addition to the most active podophyllotoxin derivatives in each series against human cancer cell lines and insect pests listed in the tables, the structure-activity relationships of podophyllotoxin derivatives as cytotoxic and insecticidal agents are also outlined. Future prospects and further developments in this area are covered at the end of the Review. We believe that this Review will provide necessary information for synthetic, medicinal, and pesticidal chemistry researchers who are interested in the chemistry and biology of podophyllotoxins.

Abstract
4beta-(Benzoylthioureido)-4'-demethyl-4-desoxypodophyllotoxin (HY-2), a synthetic aroylthiourea analog of podophyllotoxin, was identified as a novel DNA topoisomerase II inhibitor. It exhibited significant antiproliferative effect on seven cancer cell lines and induced HCT-116 cells apoptosis. DNA flow cytometric analysis revealed that HY-2 induced cell cycle arrest at G2/M phase. Western blot analysis indicated that phosphorylation of cdc2 protein was decreased after HY-2 treatment, which might be the main cause for G2/M phase arrest.

Abstract
The novel aroylthiourea analogue of podophyllotoxin HY-1 (4β-[benzoyl-thioureido]-4-deoxypodophyllotoxin) was synthesized in our laboratory with the aim of developing multitargeted DNA topoisomerase II inhibitors. The compound showed significant antiproliferative effects on seven cancer cell lines and induced G2 /M phase arrest in HCT116 cells. Moreover, HY-1 showed a potent inhibitory effect on topoisomerase II-mediated kinetoplast DNA decatenation in a dose-dependent manner. Our results showed that cdc2 phosphorylation and decreased cdc2 kinase acitivity through the ATR-Chk1-Cdc25C and Weel pathways were the central mechanisms for G2 /M phase arrest in human colon cancer cells.

Abstract
BACKGROUND Podophyllum hexandrum Royle (P. hexandrum) is a perennial herb and widely used in clinic. The present study was designed to separate and identify the biochemical composition and antioxidant capacity of extracts from P. hexandrum rhizome. METHODS The ethyl acetate and ethanol extracts from P. hexandrum rhizome were analyzed by GC-MS (gas chromatography-mass spectrometry), and the antioxidant capacity of the extracts and the components was tested by using the DPPH (2, 2-diphenylpicrylhydrazyl) and FRAP (Ferric reducing/antioxidant power) assays. RESULTS The rhizome extracts had greater antioxidant capacity than the petiole extracts in DPPH and FRAP assays. About 16 kinds of main reactive oxygen components were identified in the extracts. Components of PADE (Phthalic acid, diisobutyl ester), BADE (1,2-Benzenedicarboxylic acid, diisooctyl ester), Polyneuridine, PODD (Podophyllotoxin, deoxy), β-Sitosterol and POD (Podophyllotoxin) showed the antioxidant capacity in some degree. PODD, POD, and Polyneuridine showed stronger antioxidant capacity with the IC50 and FRAP values of 9.61 ± 0.81 and 2923.98 ± 21.89 μM, 9.98 ± 0.24 and 2847.27 ± 14.82 μM, and 13.37 ± 0.35 and 2404.32 ± 36.88 μM, respectively, than the positive control ASA (Ascorbic acid) with the values of 60.78 ± 1.22 and 1267.5 ± 30.24 μM (P < 0.01). CONCLUSIONS PODD, POD, and Polyneuridine are very critical for the antioxidant capacity in the extract of P. hexandrum rhizome. These results provide useful biochemical basis and information for the potential use of this plant.
